Why Electric?

Battery Electric Equipment allows a mine to unlock a trifecta of benefits: improved health and safety, reduced greenhouse gas emissions, and decreased operating costs. Removing emissions from even a few metres, never mind kilometres, below the ground requires massive ventilation infrastructure—shafts, equipment, and enormous amounts of electricity to run the machinery.

“Moving away from diesel and by achieving other reductions associated with the use of clean technologies, (a typical mine) can avoid more than 7,500 tons of CO2 and eliminate 3 million litres of diesel fuel, 1 million litres of propane and 35,000 megawatt hours of electricity every year.”

CHALLENGES

Maclean Engineering tasked MEDATECH with the challenge of delivering a working Battery electric powertrain in an extreamly short timeline.

Although these machines have the advantage of being plugged-in when they are drilling our design allowed the machines to drill from battery which is also a first in industry.

The success of this machine weighed heavily on the performance and safety of the batteries. MEDATECH formed a partnership with the leading Lithium Ion battery producer in the world that has both the best energy density and charging performace.

The machine are implemented in underground mining where charging infrastructure is difficult to manage

SOLUTIONS

Using a design preparred for Ontario Power Generation MEDATECH was able to implement the battery technology extreamly fast for the MacLean machine

Instead of offering multiple charging station MEDATECH devised a plan of mobile on-board charging that travels with the machine. This gave the units ultimate flexibility.

Project Team was highly integrated with the MacLean engineering organization, aligned to objectives and committed to delivery.

Amid the downturn in Mining this development allowed Maclean Engineering to gain market share in a new sector

HIGHLIGHTS

Drill from Battery is the first in industry

Advanced battery technology is both the safest and most energy dense.

Fast charging and ultimate flexibility with on-board charger.

MacLean Engineering landed a large order for the conversions to the GOLDCORP borden project. The units provided are the only truly battery electric utility machines being delivered to this site.
